Definitions

  • One object of the invention is to provide a grinding machine of this character having a discharge orifice with means for preventing injury to a finger of the operator through its insertion into thedischarge orifice.
  • Another object is to provide a grinding machine of this character with means for automatically controlling the size of the discharge orifice to prevent injury to the fingers of the operator.
  • Fig. 2 is a section on the line 22 of Fig. 1, partly broken away and with the rotatable grinding member removed;
  • the sleeve member 51 Adj accnt its lower portion the sleeve member 51 is provided with an opening 60 which substantially corresponds in size and shape with the discharge orifice 61 provided by the lower portion of the casing.
  • the sleeve 51 thus forms a closure member for the discharge orifice, the hole 60 being positioned in the cylindrical wall of the member 51 so that when the pin 55 is at the bottom of the slot the discharge orifice will be practically closed by the portion 62 of the sleeve adjacent the hole 60.
  • the spring 58 therefore normally maintains the discharge orifice substantially closed, but
  • a casing having a discharge/orifice, a pair of relatively rotatable grinding means in said casing, means for driving one of said grinding means, a closure for said discharge orifice,
